How to Disable the Task Manager for Limited or Standard Accounts in Windows

regedit Last week, I was configuring my old installation of Windows XP when my entire facilities was hit by thunderstorms and some surge protections fails during that day. Lighting strikes near our house and luckily, only few of my computers was affected and $133 dollars worth of electronics equipment was damage.

But It costs two days of work and redesigning my equipments.

Anyway, unexpected moments happened and I’ll start all over again and dig more some topics regarding useful tips for everybody.

Manually Disable or Remove the Task Manager from the List for Limited Accounts

This security policy tip is very useful for schools, internet cafes, small business and shared computers at home.

From you Limited or Restricted User Account, Open your Windows Explorer > go to \Windows folder > regedit.exe > Right-Click and Choose “Run as…” option

Open the program for accounts with administrative privilege

hkeyusers

 

In this example, I want to disable the Task Manager for the User Account named Sharedaccount.

Once the Registry editor is opened, we need to verify and find the corresponding SID folder for the account.

 

 

How to get the corresponding SID Folder for the Specific User Account

go to these registry location to get first the corresponding SID key for the User

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

Find the corresponding SID by checking those folders for the Sharedaccount Value

S-1-5-21-825345543-318236825-1802669531-1003

CHECK THIS VALUE

ProfileImagePath

%SystemDrive%\Documents and Settings\Sharedaccount

Now, we have verified that the SID for the Sharedaccount user is S-1-5-21-825345543-318236825-1802669531-1003

  • Open this registry Location to restrict launching of task manager

HKEY_USERS\S-1-5-21-825345543-318236825-1802669531-1003\Software\Microsoft\Windows\CurrentVersion\Policies

  • If System subfolder key doesn’t exists, create the folder and Right-Click the folder key > New > DWORD (32-bit) Value

disabletaskmgr

  • type DisableTaskmgr, double click and change the value to 1

Try by pressing CTRL+ALT+DEL or CTRL+SHIFT+ESC
